Update.
* sysdeps/pthread/pthread.h: Add prototypes for pthread_spin_init,
pthread_spin_destroy, pthread_spin_lock, pthread_spin_trylock,
and pthread_spin_unlock.
* sysdeps/pthread/bits/pthreadtypes.h: Change struct _pthread_fastlock
into pthread_spinlock_t. Change all uses.
* spinlock.c: Implement pthread_spin_lock.
Rename __pthread_unlock to __pthread_spin_unlock and define weak
alias for real name.
Define pthread_spin_trylock, pthread_spin_init, and
pthread_spin_destroy.
Change all uses of _pthread_fastlock to pthread_spinlock_t.
* spinlock.h: Rename __pthread_unlock to __pthread_spin_unlock.
Change all uses of _pthread_fastlock to pthread_spinlock_t.
* Versions [libpthread] (GLIBC_2.2): Add pthread_spin_init,
pthread_spin_destroy, pthread_spin_lock, pthread_spin_trylock,
and pthread_spin_unlock.
* cancel.c: Use __pthread_spin_unlock instead of __pthread_unlock.
Change all uses of _pthread_fastlock to pthread_spinlock_t.
* condvar.c: Likewise.
* internals.h: Likewise.
* join.c: Likewise.
* manager.c: Likewise.
* mutex.c: Likewise.
* pthread.c: Likewise.
* rwlock.c: Likewise.
* semaphore.c: Likewise.
* signals.c: Likewise.
